Still fierce at 38! America's Next Top Model host Tyra Banks parades her super curves in a cut-away swimsuit

Her weight has fluctuated over the years but at 38, Tyra Banks is more 'fierce' than ever.

The America's Next Top Model host looked in great shape as she posed in a swimsuit while on holiday this week.

While all eyes were no doubt on her killer curves, the star drew attention to another part of her anatomy - her famously high forehead.

Tyra recently revealed she is on a mission to encourage women to embrace their imperfections.

'This is who I am! I'm Tyra Banks and
I have cellulite!' she told Us Weekly last month. 'That makes me
"flawsome' because I own it as part of what makes me unique.

'My main mission is to get girls to
realize their inner and outer beauty and have high self-esteem with
both,' she added. '"Flawsome," for me, is about being flossy, amazing
and awesome with our flaws and celebrating those, too.'

But one subject outspoken Tyra has remained quiet on is her rumoured new love interest.

She
has reportedly embarked on a relationship with former boxer Robert
Evans - who is to be a judge on her show America's Next Top Model.

Earlier
this month they were seen enjoying cocktails at the Palihouse in Los
Angeles, with the pair leaving for Robert's hotel room after the British
hunk had paid the bill.

A source told RadarOnline.com: 'He put his arm around her as they walked to the elevator.'

Days later, the pair enjoyed a champagne brunch at Pelican Hill in Newport Beach, where they spent a two-day break.

A source said: 'They were holding hands on the table and gazing into each other's eyes.

'You could taste the chemistry between these two!'

Earlier
this year Tyra - who split from John Utendahl after three years
together in December - was romantically linked with 25-year-old rapper
Drake.

The pair were seen
together in Disneyland, appearing relaxed and happy in one another's
company as they shared frozen yoghurt and tried out the rollercoasters.
